Hobart Bosworth both produced and starred in this rugged drama. Lars Larson (Bosworth) and John Thomas (Wade Boteler) are pals who head for the Yukon with their new wives (Irene Blackwell and Collette Forbes). The wives give birth in Nome -- the Larsons have a girl and the Thomases a boy. But Larson notices that both infants have similar birthmarks on their shoulders. He immediately assumes that his wife has been unfaithful and he swears to one day get vengeance. After 20 years, Larson's wife has died and the two men have become millionaire mine owners. Larson, however, is being cheated by one of his employees, James Curdy (William Conklin). James Bradley, another worker (Henry Hebert), threatens to expose him. Larson's daughter, Julia (Madge Bellamy), wants to marry Thomas' son, Paul (Raymond McKee), but Larson refuses to give his assent. Paul goes to Larson's yacht to plead his case on the same night that Bradley shows up to expose Curdy. But Curdy also shows up and there is a struggle. Bradley is killed, and Curdy convinces Larson that he is the murderer. Larson flees up north and Curdy sets fire to his yacht. Paul is accused of killing Larson and is sentenced to be hung. Larson, however, finds out about the trial and returns to San Francisco to save Paul's life. Curdy confesses that he killed Bradley, and Rita, Larson and Thomas' half-breed servant (Lule Warrenton), reveals that she switched Julia and Paul at birth because Thomas so desperately wanted a boy. Somehow this assures everyone that Paul and Julia are not half-brother and sister, and they are wed.
